摘要
首先对在光网络中进行自适应色散补偿的必要性进行了简单的说明,然后综述了运用光栅的应力特性、压电特性 和温度特性而实现的色散补偿量可调谐的结构,并对各种结构的优缺点进行了分析。
It is necessary for the future Optical-fiber Network to compensate dispersion adaptively. A few schemes to provide the tunable dispersion compensation based on different kinds of fiber gratings was introduced in this paper. These schemes take advantages of the strain, stress and temperature characters of fiber gratings. Some evaluations for these schemes are also given.
